Hello my name is Alex,
I have followed the no post guide on this forum but have not solved my problem, specially since I get unconsistent results.
My 2,5 year old Dell inspiron 6400 (e1505) out of warranty
CORE 2 DUO T7200
15.4" WXGA (1280X800)
RAM 2048MB (2X1024) 667MH
120GB SERIAL ATA
9 CELL 85W/HR LI-ION
ATI MOBILITY RADEON X1400
WINDOWS MEDIA CENTER XP SP3
About a month ago it started to fail to POST. after several attempts it would finally boot. If I restart it works fine, only on Cold boots will it fail to POST, and after several attempts or just leaving the fans running for 10 minutes and booting again it will work.
When i works i have run full dell BIOS diagnostics and everything is fine.
By pressing mute and power i get LED feedback on the POST failure

I normally get a still flash flash code which means:
Description: Turning on the LCD panel (after video configuration).
Actions:
1. Reseating the LCD cable.
2. Replacing the LCD panel.
3. Replacing the video card.
I have followed the no POST guide on this site,
Dispersing internal Voltage
resetting the CMOS (by extracting the coin battery for a minute)
Switching around the RAM
Opening up the laptop and securing the lcd to video card plug
All of these produced irregular results, sometimes it works others it doesn´t.
Sometimes while pressing mute and power the computer boots into bios diagnostics mode showing a flash flash still LED code witch means
Description: The video card is preventing the system from completing POST.
Action:
1. Replacing the video card.
2. Replacing the system board.
but it boot without problems into the diagnostics test, passes all test and then boots normally into windows.
Any help will be greatly appreciated. It is not currently a fatal problem, since it always boots after 10 minutes running (without booting) But i don´t want my motherboard dying suddenly, or if it is a connection in the LCD, i would like confirmation before pulling it all apart to check loose cables. I have taken apart computers but am certainly not an expert.
Thank you
Alex
